HEATNG-CARTRIDGE,

No. &47,668.

To wll whom it may cancer-n. i

Be it known that I, ALBERT LANG, a subject of the Grand Duke of Baden, residin at Karlsruhe, in the Grand Duchy of Ba en, Germany, have invented an Improvement in Heating-Cartridges, of which the following is a specifieation.

My inventon relates to a cartridge for the rapid heating of fluids or mixtures of fluids by utilizing the whole of the heat developed by chemical reaction of the metals contained Thus high temperatures ma be create in a very short time' he drawing shows a section through the cartridge.

The Cartridge consists in the inflammable matter, the reacting material, and the protecting-head. The' inflammable matter is com sed of a sheet of magnesium or celluloid and a primary com osition consisting of an upper readily-igniti le mass 'i of magnesium with chlorate of potassium and an under mass or priming cap k, of aluminium; with a superoxid which easily delivers its oxygen, such as barium superoxid. The reacting material I consists `of an admixture of alumnium or ma esium with metallic oxids or other carbonee substances which burn The prcteeting-bed e of copper. To aoting mass d wt'h the priming comppsit ilok, e

the major portion of the plate exposed.

Speci flcation of Letters Patent. Application fllad May 10,1904. Sei-&1110207320 Patented March 19, 1907.

By igniting the plate h the primary composition 'L k is also ignited, and the mass k urns through the co per cap l and ignites the reacting material The reacting material produces' such a high temperature that the reduced netalstrickle together and fall to the bed e, which prevents them from burning through the Cartridge. 1 Said bed rapidl y conducts the heat to the material to be heated. 4

Havin now particularly described my invention, T declare that what I claim is 1. A heating-cartrdge comprising a casing, a base of slowly-fusible but freely-'conductng material therein, a heating mass d, resting on said base, the priming composition i, extending into said mass d, a primirg-cap k-.between the mass d, and the priming composition'i and a readily-combustible igniting means. i

2. A heating-cartridge conprising a casing, a base of slowly-fusible but. freely-cony ducting material therein, a heating mass d resting on said base, a copper cap l on said 4 mass d, a priming-cap k on said coper cap l,

the rimig compostion 'i on sai prmngcap and a plate ofeombustible material placed over the composition i.

In witness whereof I have my hand in presence .of two witnesses.

ALBERT LANG.
